To all whom-it vriay concern: I

Be it known that I CHARLESE. SUMMERS, a subject of theKing of GreatBritain, residing at Mannville, in the Province of Alberta" and Dominionof Canada, have invented certain new and useful Improvements inDoor-Latches; and I do hereby declare the following to be a full,-clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to-Inake and use the same.

This invention relates to latches for barn A still further obj ectoftheinvention is to provide an improved latch of the-above character forright or left hand swinging or sliding doors, which is of exceedinglyeflicient and durable structure, one that is simple and easy tomanufacture and one that can be placed upon the market at a reasonablecost.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specifically described, claimed and illustrated in theaccompanying drawings, in which- Figure 1 is a perspective view. of theimproved latch applied to a door,

Fig. 2 is a vertical section through the latch, taken on the line 22 ofFig. 1,

Fig. 3 is a detail perspective view of the locking lever,

Fig. 4 is a detail elevation of the keeper.

Fig. 5 is a horizontal section taken on the line 55 of Fig. 1.

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several views,the numeral 1 generally indicates an improved latch which is shownapplied to a door 3 and casing 4 of the ordinary or any preferredconstruction.

The latch 1 includes the supporting plates 4 and 5 which are placed oneupon the other mamma fixed position by means of-"bolts 6- which extendthrough registering apertures 7 formedfl in the ends' thereof andthrough the*door2. 'The bolts 6 also extend through: azplate-Spositioned: on the opposite side ofthe door'2 and suitable nuts 9" areturned on the: ends" of the bolts and hold the'plates againstdisplacement. The outer plate 5' is bent intermediate the" ends thereofas at'lOto space the same from the inner plate l to form" a' housing:for the" reception of: the locking." lever 11', the inner end of which.extends'beyond the outer edge .of the door and ispositioned: in: thepath of the door framecarried plate 1 2, Which will;

hereinafter be more specifically described I Thelocking lever 11;includes asubstan-- tially horizontal arm 18- and a-downwardly'extending vertical: arm; .14, whichsisa gradually-widenedf toward thelower free end thereof, which is provided with the head15. Q The head 15andthe thickened portion of;

the vertical. arm forms; weighted end which normally holds thehorizontal arm in anrelevated-positiona i a The! locking lever 11 ispivotally secured in position by means of the horizontal extension 16,formed on the inner operating handle 17. The plates 4, 5, and 8 areprovided with registering apertures for rotatably receiving thehorizontal arm 16 which has the outer end thereof reduced as at 18 and aportion thereof is made non-circular in cross section as at 19, whichportion receives the locking lever 11, whereby the lever and the arm areheld against relative movement. A suitable pin 20 or the like extendsthrough the outer free end of the arm 16 and holds the same againstdisplacement. The inner portion of the arm 16 is bent downwardly as at21 and then curved upwardly as at 22 to form the handle 17 whereby thearm may be readily rotated. An angled plate 23 has the inner portion 24thereof positioned between the plates 4 and 5 and is held againstdisplacement by means of the upper bolt 6 which extends through thesame. The outer arm 25 of the plate is provided with the aperture. 26,which registers with the aperture 27 formed in the door frame carriedplate 12. The door frame carried plate 12 is provided with an inwardlyextending slot 28 formed in the lower edge thereof which is adapted toreceive the free end of the locking lever 12, which holds the door initslocked position. The lower outer latching of the door or gate when thesame is thrown closed.

It is to be understood that a suitable pad look (not shown) ispositioned through the registering apertures 26 and 27, for positivelyholding the door or gate-in closed position against movement when sodesired.

The outer projecting end of the, horizontal arm 18 of the locking lever12 has the upper edge thereof beveled downwardlyand out wardly as at 30so that when the latch is to be used on Sliding doors, the locking leveris readily swung on its pivot so as to move under the door frame carriedplate 12 and the upper edge of the arm 13 is provided with a groove 31which is adapted to receive the upper wall of the slot 21 and holds thedoor against sliding movement. 7

From the foregoing description it can be seen that an improved latch isprovided, which is of exceedingly simple and durable construction whichis. normally held in its latched position by means of the weighted endof the lever 11 which eliminates the necessity of providing springs andthe like.

In practice, I have found that the form of my invention, illustrated inthe accompanying drt wings and referred to in the above description, asthe preferred embodiment, is the most efficient and practical;

yet realizing the conditions concurrent with the adoption of my devicewill necessarily vary, I desire to emphasize the fact that various minorchanges in details of construction, proportion and arrangement of partsmay be resorted to, when required without sacrificing any of theadvantages of my invention as set forth.

WVhat I claim as new is In a device of the class described, thecombination with a door and frame, of a latch therefor including ahousing secured to the door, a shaft extending through the housing anddoor and rotatably carried thereby, a handle formed on one end of theshaft, a locking lever carried by the shaft and having a downwardlyextending weighted manipulating handle, the opposite end of the lever atits upper surface thereof beveled downwardly and provided with a groove,and an outwardly extending plate carried by the door frame having theforward edge thereof beveled downwardly and the lower edge thereofprovided with an inwardly extending slot to receive the lever as and forthe purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
